Mechanical Belt Drive Governors
Engine governors are relatively simple devices that monitor, limit and determine engine speed under various conditions.
Belt drive governors are often retrofitted to an engine where there wasn't originally a governor. They mount on a bracket on the front of the engine and are driven by a belt between a pulley on the governor and the crankshaft pulley. Selecting the correct pulley size on the governor is important.
Belt drive governors, like all mechanical governors, will not only limit top speed (as do velocity governors) they will also allow the engine to react while under a sudden load. Because of this they are found on wood chippers and other intermittent load applications.
We supply Hoof Governors as well as governors by Governors America Corp and would be happy to answer any questions.
